Data collection program

I have a need to harvest data from a web site on a weekly basis and need a program to do the work. I currently do it with a program I wrote but I need something more robust in order to run this more often. The project is simple: download some html files and then extract the data in them and put them in a standard delimited ASCII file. The program will simply query a web site to get the html pages that are available. There are about 100 per calendar date and the need is to be able to download the files starting with the current date and going to an end date. This means downloading between 35,000 and 100,000 html files each time the program runs. The program should begin by getting the html files and storing them in a temporary folder. The second step of the process is to parse the html files and extract the data contained in them. The HTML files keep the same format and are easy to extract as they are simple lists. ALL fields must be extracted. The list have header information, so the header information must be repeated on each record of data created to ensure that the information stays together. For example, it will give the name and then a list of all the clients for that name. The extracted data must be saved in a standard ASCII file format where each field is delimited by a character to be configurable in the program (example a tab). I will then take this data and import it into a database system for processing. I do not need a program with a fancy user interface. It needs to be simple and functional. It must work on Windows XP Pro. Attached is a ZIP file containing samples of the html files as well as the web site information. The provider must submit a final program in executable format with all necessary files, and also the source code. He must have tested the program and must submit the results for one run between two dates, of a year time period (example: the provider can run the program on february 1st 2009 and put the end date february 1st 2010. The data collected must be submited to show the program works.). If the provider does a good job on this, there are several other similar projects available for him. In the future when the format of these html files changes, I will ask the provider to modify the program. This is a simple project but please only bid if you have done this type of work before and are sure you can deliver the work. I do not want to waste your time or mine. If you have questions please message me before you bid. Thank you
